This is not the most user friendly thing to do. Some sys admins
require config files (and indeed all data) to be located separately
from programs. It would be more friendly to provide the option
of defining the config file location, perhaps via an environment
variable.

Of course if the env variable is not defined you probably still need
this code for the default location, in which case Wayne's suggestion
should work. (Alternatively throw an error insisting the EV be set up)

And if you are not deploying this to more than one operating
envioronment where you know the policy then its a moot
point anyway.
